In the links on the left click "Downline." On that page near the top is a button that says, "Move Downline Members."

Remember, you can only move members once, you can only move ones you personally sponsor and the move is not reversible.

For the more advanced that are using WordPress you can also use a plugin like Redirection. With this you create a link that does nothing but redirects to a new link. Then, instead of YOUR GDI link you can put in one of your downline members GDI affiliate links. Like, if you have a JOIN GDI link on your site, you can change it to someone on your team instead of yourself. Great thing about this plugin is you can change the "target link" anytime you want. So, each day you can promote for one of your team members across your whole site by changing just one thing in the redirection plugin area.

Again, that's for more advanced users but if you understand what I'm saying and have never thought of it... well, you're welcome. And of course you can always change it to point to YOUR affiliate link as well when you want! Totally up to you. But saves having to change links across your entire site. It does the work for you! And your downline members will looooove you and this in turn will keep them in YOUR downline.
